NAME

jinfo - Generates configuration information. This command is experimental and unsupported.

SYNOPSIS


jinfo [ option ] pid


jinfo [ option ] executable core


jinfo [ option ] [ servier-id ] remote-hostname-or-IP

option: The command-line options. See Options.
pid: The process ID for which the configuration information is to be printed. The process must be a Java process. To get a list of Java processes running on a machine, use the jps(1) command.
executable: The Java executable from which the core dump was produced.
core: The core file for which the configuration information is to be printed.
remote-hostname-or-IP: The remote debug server hostname or IP address. See jsadebugd(1).
server-id: An optional unique ID to use when multiple debug servers are running on the same remote host.

DESCRIPTION

The jinfo command prints Java configuration information for a specified Java process or core file or a remote debug server. The configuration information includes Java system properties and Java Virtual Machine (JVM) command-line flags. If the specified process is running on a 64-bit JVM, then you might need to specify the -J-d64 option, for example: jinfo-J-d64 -sysprops pid.

This utility is unsupported and might not be available in future releases of the JDK. In Windows Systems where dbgeng.dll is not present, Debugging Tools For Windows must be installed to have these tools working. The PATH environment variable should contain the location of the jvm.dll that is used by the target process or the location from which the crash dump file was produced. For example, set PATH=%JDK_HOME%\jre\bin\client;%PATH% .

OPTIONS

no-option: Prints both command-line flags and system property name-value pairs.
-flag name: Prints the name and value of the specified command-line flag.
-flag [+|-]name: enables or disables the specified Boolean command-line flag.
-flag name=value: Sets the specified command-line flag to the specified value.
-flags: Prints command-line flags passed to the JVM.
-sysprops: Prints Java system properties as name-value pairs.
-h: Prints a help message.
-help: Prints a help message.
